PENNSYLVANIA, ASSIGNOR TO THE SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No.,593,'742, dated November 16, 1897. Application met April 1,1897. 'seria1r0.eso,2'7e. (No modem To all whom it may concern.-

Be it known that I, THOMAS C.- DILL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Shaft-Han gers, of which the following is a specication.

One'object of my invention is to construct a light but extremely strong shaft-hanger.

A further object is to simplify the construction oi' the same by making its parts interchangeable, so that the assembling and titting together or taking apart of the hanger can be readily accomplished; and a still further obj ect is to permit of the use of the hanger in any desired position.

These objects I attain in the manner hereinafter set forth, reference being had to the accompanyingdrawings, in which- Figure lis a side view of a shaft-hanger constructed in accordance with my invention. Fig. 2 `is a transverse section of the same, partly in elevation. Fig. 3 is a plan or top view of the bracket-plates of the hanger. Fig. 4 is a sectional view on the line :11, Fig. 2; and Fig. 5 is a sectional plan view on the line y y. Fs- 2- The hanger consists, essentially, of depending rods 1 1, bracket clamp-plates 2 2, boxholding clamp-plates 3 3, and box supporting and guiding blocks 4 4. l

The depending rodsl 1 are in order to se-v cure lightness made in tubular form and preferably flattened or of oval cross-section, as shown in Fig. 5, these tubesY being slightly curved longitudinally, so as to iiare outwardly at their upper ends and thereby increase the area of support.

The bracket clamp-plates 2 2 t snugly to the upper ends of the rods 1 1 and are firmly clampedthereupon by bolts 5,passing through both bracket-plates and rods and provided with nuts 6. The bracket-plates are preferably provided with offset joints, as shown in Fig. 1, and with slots 7 for the reception of bolts 9, whereby the brackets are secured to the joist, Stringer, ceiling, floor, post, pedestal, or other support for the hanger, lateral adjustment of the hanger on thesebolts being permitted by the slots 7 and the locking of the hanger in position after adjustment being provided for bymeans of set-screws 10,

which bear upon the bolts 9 and are adapted to threaded openings formed by recesses in the opposite halves of the outer portions of the bracket clamp-plates. Hence shifting of the hanger is prevented even should the nuts on the bolts 9 become loose.

The box-holding plates 3 have jaws 1l, which fit snugly upon the rods 1 and are firmly clamped thereupon by means of bolts 12 passing through the clam p-plates on the inner sides of said rods. I

The clamp-plates 3 are recessed for the reception of the box supporting and guiding blocks 4, which have at the inner ends tapered sockets for the reception of the tapered ribs 13 upon the upper and lower sides of the divided shaft-box 14, these ribs and sockets being curved longitudinally, as shown in Fig. 4, so that the shaft-boxes are free to adjust themselves to the alinement of the shafts. The blocks 4 can be adj usted vertically in the clamps 3 by means of screw-stems 15, which are adapted to threaded openings in lthe blocks and pass through openings formed by recessing the top and bottom halves of the clamping-plates 3, an inner collar 16, and an outer lock-nut 17 serving t0 secure the bolts in position after any adj ustment of the blocks 4 has been eected, loosening of the nuts 17, however, permitting the turning of the screws 15 when further adjustment of the blocks 4 is necessary.

The inner collars 16 are in the present instance composed of nuts pinned on the screwstems 15, but any available form of ange or collar may be used.

The parts of my improved shaft-hanger can be readily assembled, as the hanger-rods, the parts of the respective clamps, and the blocks 4 are interchangeable, ordinary bolts being relied upon for securing the parts together, and there being no weakening of the hangerrods by the cutting of screw-threads thereon. Hence said rods can be made much lighter than usual without detracting from their necessary strength.

The upper and lower halves of the shaftbox have laterally-projecting wings 19, which when the two halves of the box are brought together form lugs of the same character as the lugs 13, and are, like the latter, adapted to enter the sockets of the blocks l. Hence the hanger can be used either as a depending hanger, as an upwardly-projecting pedestal, or as a post-hanger projecting laterally, the cups 20 being upi'ight in either case when grease is used, or, if desired, being reversed and used in connection with depending oilcups and having feed -wicks passing up through them to the bore of the box. In whichever position the box is used the blocks l serve not only to support the box, but also to hold the two part-s of the saine together. rIlius when the box is in the position shown in Fig. 2 the two parts are held together by the direct pressure of the blocks l, and when the wings I9 are adapted to the openings of the blocks the two parts of the box are held together by the clamping action of said blocks upon said wings.

IIaving thus described my invention, I claim and desire to secure by Letters Patent- I. The combination in a shaft-l1anger,of opposite hanger-rods, shaft-boX-holding clampplates having jaws for embracing said rods, and bolts securingsaid clamp-plates together, substantially as specified.

2. The combination in a shaft-hanger, of the hanger-rods, bracket clamp-plates having jaws for embracing said rods, and bolts for securing said clamp-plates together, substantially as specified.

The combination in a shaft-hanger, of the hanger-rods, bracket clam p-plates having jaws for embraein g said rods and bolts passing through said jaws and through the rods and serving to secure the clamp-plates together and to the rods, substantially as specilied.

4. The combination with a shaft-hanger bracketliaving laterally-elongated slots, with secu ring-bolts passing through said slots, and set-screws projecting into said slots and bearing against the securing-bolts to lock the bracket thereto, substantially as specified.

5. A shaft-hanger in which are combined hanger-rods, bracket clamp plates having jaws for embracing said rods, and laterallyelongated slots, supporting bolts passing through said slots7 bolts passing through the bracket clamp-plates and serving to secure the saine together and to the hanger-rods, and adjusting and locking set-screws adapted to threaded openings in the bracket clam p-plates and projecting into the ends of the elongated slots therein so as to bear upon the supportingbolts which pass through said slots, substantially as specified.

G. The combination in a shaft-hanger, of

the hanger rods, shaftbox-holding clampplates having jaws for embracing said rods, bolts for secui'ing said clamp-plates together, and shaft-box supporting and guiding blocks contained in recesses in said clamp-plates, substantially as specified.

7. The combination in a shaft-hanger, of the hanger-rods, shaft-box-holding clampplatcs having jaws for embracing said rods, bolts for securing said clamp-plates together, shaft box supporting and guiding blocks adapted to recesses in the clainp-plates, and adj ustin g-screws carried by said clamp-plates and engaging said blocks, substantially as specified.
